摘要: The nonlinear evolution of the diocotron instability a planar electron strip is investigated analytically by means shearing mode for solution initial and boundary value problems. method based on sheared spatial coordinates which account motion flow in electrostatic field unstable modes addition to unperturbed transformed shear coordinates. time evolutions are studied obtained solutions perturbed potential include two effects—the effect distortion boundaries coupling nonmodal modes. It was proved two-dimensional particle-in-cell simulation that developed theory valid as long basic does not change frequency growth rate linear
